You can put this solution on YOUR website!
1 pound = 16 ounces

5 pounds = 80 ounces (multiply both sides by 5)

----------------------------

$54.45 to buy four 5lb. containers

so

$54.45 to buy four 80 oz containers

So that means that $54.45 will get you 4*80 = 320 ounces of cheese total

-------------------------------

(54.45 dollars)/(320 oz)

(54.45/320)*(dollars/oz)

0.17015625 dollars/oz

17.015625 cents/oz

17.02 cents/oz

So it's roughly 17.02 cents per ounce
